Connecting the LEX unit to the REX unit
To ensure proper operation, it is recommended that only solid core Cat 5e or better, Unshielded Twisted Pair cabling
be used to connect the LEX unit to the REX unit. The cabling must have a straight-through conductor
configuration with no crossovers, and must be terminated with 8 conductor RJ45 connectors at both ends. The
combined length of any patch cords using stranded conductors must not exceed 10m.
With Surface Cabling
1. Plug one end of the Cat 5e cabling (not included) into the Link port (RJ45) on the LEX unit.
2. Plug the other end of the Cat 5e cabling into the Link port (RJ45) on the REX unit.
With Premise Cabling
1. Plug one end of a Cat 5e patch cord (not included) into the Link port (RJ45) on the LEX unit.
2. Plug the other end of the patch cord into the Cat 5e information outlet near the Host computer.
3. Plug one end of the 2 nd Cat 5e patch cord (not included) into the Link port (RJ45) on the
REX unit.
4. Plug the other end of the 2 nd patch cord into the Cat 5e information outlet near the USB device.
The maximum length of the Cat 5e cable, including patch cords, must not exceed 100 meters. The combined
length of any patch cords using stranded conductors must not exceed 10m.
Checking the installation
1. On the LEX and REX units, check that the Power, Host and Link LEDs are on and that the Activity LED is
blinking. If the Link LED and Activity LED are permanently off then the cabling between the LEX and
REX unit is not installed properly or is defective.

been installed correctly you should find it listed as a Generic USB Hub.
